In countries nearer to polar region, the roads are sprinkled with $\mathrm{CaCl}_{2}$. This is
- Correct answerAto minimise the wear and tear of the roads
- Bto minimise the snow fall
- Cto minimise pollution
- Dto minimise the accumulation of dust on the road
Solution
In countries nearer to polar region, the roads are sprinkled with $\mathrm{CaCl}_{2}$ because $\mathrm{CaCl}_{2}$ decreases the freezing point of ice and therefore, minimise the wear and tear of the roads.
Hence, the correct answer is option: 'A'.
